APPARATUS AND METHOD FOR ELECTRO-OPTICAL SPLIT IMAGE FOCUSING |
摘要 |
Provided are an electro-optical split image focusing apparatus and method through which an in-focus position of a photographed plane with respect to the image of a subject can be detected with accuracy and speed. The apparatus comprises at least one electro-optical element disposed along an optical axis between a subject and a photographed plane. The electro-optical element is characterized by a refractive index that varies with distance along a perpendicular to the optical axis when a voltage is applied. An image of the subject is transmitted toward the photographed plane through the electro-optical element.
